The Schedule referred tn x. these Letters Patent and making part of thesaine.

Y of my instrument for curingdiseases by vacuum.

The nature of my Ainvention consists in the employment of a case,made'of any suitable material, for the reception of the parts to betreated, and in providing the said case, at'its upper end, with rubbercap and band, so that the case may t air-tight around the limb or joint,to be treated in combination with such other-devices, the peculiarity ofwhich will be hereinafter fully set forth.

'Io enable others skilled in the art to which my invention appertains,to make and use the same, I will now describe its construction andoperation.

In the accompanying drawing- A represent a case, made of any suitablematerial, size, and shape, to be placed around the limb or joint to betreated. Y

O is arubber cap, which is. first passed Iup upon the limb to the pointdesired, fitting loosely around the same, and being made air-tight bymeans of the rubber strap or bandrB, one end of which is secured, to thecap G, and the other end wound tight around the limb, half overlappingthe perpendicular band of the cup, and half being applied to the surfaceofthe limb.

D is a hinged wooden cap, adjusted below the rubber cap O on the limb,and enveloped by the rubber cap O.

The case A is then placed upon the limb.

The hinged cap D, enveloped by the rubber cap O, enters the mouth ofthecase A, which is provided, at its mouth, with a'tlange, b, surmounted bya rubber ring, which is wedged in tightly between lthe cap and flange,making it,'at that point, perfectly air-tight, the cap being held in itsplace by means of the three catches, d d d, on the upper end of case orreceiver A.

The more the exhaustion, the firmer is the cap wedged into the mouthofthe case or receiver, and the more perfect the joint.

E is a tube, attached to the outer surface of the receiver A, to whichis attached the air-pump, for the purpose of exhausting the air from thecase. v

Having thus described my invention,

What I claim as new, and desire to secure byLetters Patent, is' Y lV"Ihe combination of the case Awith the rubber cap C, hinged cap D, bandB, and catches d i d, all arranged to operate substantially inthe mannerand for the purpose described.

In Atestimony that I claim the foregoing as my own, I aix my signaturein presence of two witnesses.
